I've been told my antifreeze leak is coming from my freeze out plugs. The claim is there is much, much, labor at replacing these plugs $$$$$$. I've done some work before and I'm fairly handy. Is this a job for me? Where to find directions ( Chilton Manual)?

Actually replacing the plugs isn't hard at all. It's GETTING to the plugs that's the huge problem. First find out which ones are leaking and see what's in the way. Then you can decide if you even want to try.
